help i cant free the exhaust from the manifold got the stud nuts off no probs but cant get the exhaust to part from the manifold any tips advice before i do damage
Wide blunt drift into the gap between the loose collar flange and the head where the studs are......soak it in WD40 first.....don't damage the head though.......or simply try knocking the flange away from the head. Order some collar pairs while you are at it, because they will be buggered I reckon....they aren't too £ssss
most of all patience but as said plenty freeing fluid ie wd40 and maybe a bit of heat once it starts moving keep going a little bit at a time
I would run the engine up to temp (in current state - less manifold nuts) and then turn off engine/saturate studs and flange mating face (as best you can) with penetrating fluid.
WD40 isn't a freeing fluid, it's just a water dispersant. Better off using PlusGas (try Amazon or eBay) if you want to free off rusted in stuff. That's what I've experienced anyway.
This works: Look at this on eBay SOUDAL DEGRIP ALL 400ML SPRAY PENETRATING OIL DISSOLVES RUST & CORROSION | eBay
I was only thinking today as removing some decals that a heat gun is one of my favourite tools. Really is useful. Wouldn't be without one now.
